rosin-cam) AUTOMAT.

To all whom it may concern: 1

Be it known that L-BERNHARD GREBE, a subject of the Emperor .of Germany, and a resident of Dresden, Germany,- Elisenstrasse 72, have invented certain new and useful Improvements in Post-Card Automats, of

window within the casing of the automat.

In the heretofore known automate of this kind the salable cards were arranged in special card-holders or the like disposed one above'the other and being moved by means of levers or the like.

The present invention now consists in the cards being loosely arranged in the form of a pile within a special compartment of the automat wherefrom they are brought within the sight of the buyer and returned to said pile if the buyer wishes to see. an-

other card; finally the chosen card maybe removed from the automat by means of a guide-bar.

In the annexed drawings the subject matter of the present application is represented by way of example in two forms of execution, and therein- Figure 1 represents the automat with a postcard to be seen in the window of the casing.

Fig. 2 shows the automat in section.

Fig. 3 represents the automa t in working position.

Fig. 4 shows'the pile ofpostcards, one card being halfwaylifted.

Fig. 5 shows a modified form of the device in which the cards after exhibition are returned to another pile.

Fig. 6 shows the cam and rack mechanism for delivering acard, and,

Fig. 7 shows in detail the transport roller, and link used in the form shown in Fig. 5. In the drawings 1 is the receptacle for the postcards 2 which abut with their upper edges against the rollers 3 and 60, which latter simultaneously serve as guide-rollers. 4 is a roller mounted on springs and 5 is a rotatable roller. 6, 7 8 and 9 are likewise rollers. 10 is a support for the postcards when exhibited, 11 the compartment of exhibition within the automat; 12 is a guide rotatable.

16 which will be caught and retained by the nose 17 of the arm 18 which is rotatable about point 19..

20 is a movable guide connected to guide 12. 21 is the lower end of the coin channel 15. 22 is the receptacle for the coins, 23 a guide and 24 a lever with a nose 33 which lever is rotatable about 25. 26 is a slot provided in the lever 24, and in said slot moves the pin 27 provided on arm 18. 28 1s a wheel having teeth only on a part of its circumference.

29 is a lever swinging about 30 and having a nose 31 which projects into the channel 15 forv the coins. The lever abuts with its lower end 32 against the guide 23 which is fixed to the wheel 28. 34 is a toothed wheel.

The roller 3 is connected to the drivewheel 61 by a fast coupling and the roller 60 in the same way to the drive wheel 62 and the roller 5 to the drive wheel 63. In order to maintain all these three rollers in the same speed of rotation the wheels 64 and 65 are interposed. The drive wheel 63 is fixed on the roller 5 near the toothed wheel 34. Opposite the roller 5 a stripper 66 is arranged which is adjustable by means of the lever 67.

In the second form of execution 35 is a roller provided with rubber tongues 36, 37, 38, 39 and 40 are guide-rollers, 41 is the exhibition compartment, 42 a roller with a tongue 43. 44 is a roller with a groove 45. 46 is a link oscillating about point 47 and provided with noses 48 and 49, which knock against flaps 50 and 51.

52 and-53 are the compartments for the postcards. 54 is a chain for connecting the rollers 42 and 40. 55 is a rack-mechanism. 56 the channel for the coin.

The mode of operation of the form of eXecution according to Figs. 1 to 4 is as follows:

The toothed wheel 28 and the toothed wheel 34 are normally out of connection.

By means of a crank handle the roller 5 will be rotated and therewith the drive-wheel 63 and the toothed wheel 34. By means of the interposed wheels 64 and 65 the wheels 62 and 61 are moved by the drive wheel 63 and hereby the rollers and 3 will be set in motion as they are rigidly connected to the pinions 62'and 61.

The direction of rotation of the rollers is such. that the card grasped by the rollers is Janna and 60 move the card against the roller 4L which is mounted on springs in order to conform to the thickness of the card. The card then passes between roller 5 and stripper 66 and is brought into the exhibition compartment. As soon as the lower edge or the card leaves the rollers 6 and 7 the card lies against roller 9 and falls on account of the overweight at the upper edge backwardly against the support 10. The lower edge of the card now lies between rollers 6 and 8. In further moving the crank the card passes between the rollers 6 and 8 and falls over guide 12 into the compartment from which it was taken in order to be exhibited. 1

The rollers 6 and 8 are in fast connection with the drive wheels (38 and 69 which obtain their movement of rotation from the pinion 34.

If one desires to buy a card being exposed in the compartment of exhibition, a coin is to be pressed into the slot 15 whereby the nose 31 of lever 29 is pressed out 01 the channel 15. Hereby the lower end 32 0t lever 29 acts against the guide 23 which is in fast connection with the wheel 28 and moves the same until its teeth engage the toothed wheel 34. Upon further rotation of the wheel 341:

the toothed wheel 28 will be rotated, and by means of the guide 23 the lever 2 1 is pressed downward.

Meanwhile the coin 16 has reached nose 17 and is retained thereby. By depressing the lever 2a the latter moves around point 25 and its upper end moves by means of its slot 26 the pin 27 of the arm 18 in forward direction. Hereby the nose 17 presses the coin 16 against the uide 20 and moves this latter in a forward direction. As the guide 20 is connected with the guide 12, the latter will necessarily move around point 13 and takes up such a position as to allow the post card moving downward, to leave the automat through the opening 1 1.

During further rotation pushed in backward direction, so that nose 17 will release the coin, so that the latter drops into the receptacle 22.

The mode of operation of the form ofexecution according to Figs. 5 to 7 is as follows:

By rotating the roller 35 the lowermost postcard is brought out of the compartment 52 by means oi the rubber tongue 36 and moved upward, passing between rollers 37 and 38. During the further rotation of the roller 38 the lower edge of the card en-. ters between rollers 38 and 39 and is brought into the compartment 53. In order to secure the transport of the card into said compartment roller 4% will be rotated. The groove the toothed wheel, 28 is rotated, the guide 23 pushes the nose 33v of the lever 2 1 and presses the upper part or lever 24; backwardly. Hereby arm 18 is also 45 of the same then seizes the point ofthe triangular link 16 and oscillates the same in one or the other direction as may be necessary, so that nose 18 or 19 pushes the flap 50 or 51 backward, whereby the card drops down without any difficulty.

If a card is to be delivered from the auto mat a coin is brought into the channel 56. lhis coin releases the raclemechanism 55, whereatter the wheel 12 is actuated'by the drive-chain 54: and the tongue 43 will push the card through slot 57 out of the automat.

As the whole mechanism is very small and room is still left within the apparatus an automat for cigarettes or chocolates may be provided in the same.

The rollers serving to move the postcards to the exhibition compartments may be covered with rubber or the like.

It is evident that the described automat may not only be used for postcards but also for, for instance insurance-policies, books and all kinds of articles which one may wish to sell by means of automats.
